  Japanese Patent Laid-Open No. 2007-210462 sets a normal display for displaying characters in all areas of the display device when the vehicle speed is less than the switching speed, and displays when the vehicle speed is equal to or higher than the switching speed. There is described a vehicle display control device that sets a simple display that displays a small display area out of the character size of the device in an unreadable state (the font is set to “·”).

Japanese Patent No. 3848601 JP 2007-210462 A

  In the technique of the above-mentioned Japanese Patent No. 3848601, display is always performed with a simple expression while the vehicle is traveling. However, when the vehicle is traveling at a low speed, the driver may have a margin for visually recognizing the display in the descriptive expression, so it is better to display in the descriptive expression than in the simple expression. It may be desirable.

  Further, in the technology disclosed in Japanese Patent Application Laid-Open No. 2007-210462, the display mode is switched only depending on whether or not the vehicle speed is equal to or higher than the switching speed. Aspect changes frequently. For this reason, a driver | operator's visual field may be flickered and a driver | operator's driving | operation may be prevented.

  The present invention has been made in view of the above circumstances, and if there is room for visually recognizing the detailed display, the driver can surely visually recognize the detailed display without being limited to when the vehicle is stopped. An object of the present invention is to provide a vehicular display device that can prevent unnecessary switching from simple display to detailed display.

  In order to achieve the above object, a vehicle display device according to a first aspect of the present invention includes a display means, a display control means, a traveling state detection means, a driving operation detection means, a visual margin determination means, a visual intent. Determination means.

  The display means is disposed in the passenger compartment and is visible to the driver of the vehicle. The display control means switches the predetermined information notified to the driver between the detailed display and the simple display in which the amount of information is more limited than the detailed display, and displays the information on the display means. The traveling state detection means detects the traveling state of the vehicle. The driving operation detection means detects the driving operation of the driver. The visibility margin determining means is based on the traveling state of the vehicle detected by the traveling state detecting means to determine whether the driver is in a visually recognizable state with a large margin for visually recognizing the display means or a visually unseen state with a small margin. Judgment. The visual intent determination means determines whether the driver is in a visual request state that is likely to be intended for visual recognition of the display means or is in a visual non-request state that is unlikely to be intended for visual recognition. The determination is made based on the driving operation of the driver detected by the operation detecting means.

  The display control means determines that the visual margin determination means is in a visible state in a state where predetermined information is displayed on the display means by simple display, and determines that the visual intent determination means is in a visual request state. In such a case, the simple display is switched to the detailed display, and the simple display is displayed when it is determined that the visual margin determination means is in a state incapable of visual recognition or when the visual intent determination means is determined to be in a visual non-request state. continue.

  The traveling state detection means detects the vehicle speed of the vehicle, for example.

  The driving operation detection means may detect a plurality of driving operations for determining the visual recognition required state, for example, whether the brake pedal is operated, whether the side brake is operated, or the gear stage. Which state is detected.

  For example, the visibility margin determining means determines that the vehicle is visible when the vehicle speed detected by the traveling state detecting means is equal to or lower than a predetermined value, and is not visible when the vehicle speed exceeds a predetermined value. It is determined that it is in a state.

  The visual intent determination means is in the visual recognition request state when any one of the plurality of driving operations detected by the driving operation detection means for determining the visual recognition request state satisfies a predetermined condition. It may be determined that there is a visual recognition non-request state when all driving operations do not satisfy a predetermined condition. In this case, for example, when any one of the brake pedal being operated, the side brake being operated, or the gear position being neutral is detected, it is determined that the state is in the visual recognition required state. When none of them is detected, it is determined that the visual non-request state is present.

  In the above configuration, when the driver is in a visually recognizable state with a lot of room for visually recognizing the display means, and the driver is in a viewing request state where the driver is likely to intend to visually recognize the display means, the simple display is detailed. Switch to display. Therefore, even if the vehicle is traveling, the driver who intends to visually recognize the display means will stop the vehicle if the driver does not lose the safety of driving by viewing the detailed display. Detailed information can be confirmed by the detailed display without being limited to the inside.

  In addition, when the driver is in a state where the driver cannot visually recognize the display means, the simple display with a limited amount of information is continuously maintained. Thereby, since a driver | operator can grasp | ascertain the information displayed on the display means in a short time, a driver | operator's driving | operation is not prevented.

  In addition, when the driver is in a visual non-request state where the driver is not likely to visually recognize the display means, the simple display is continuously maintained regardless of whether the driver has a large or small margin for visually recognizing the display means. The For this reason, when the driver does not need the detailed display, unnecessary switching from the simple display to the detailed display is performed and the driver's view is not flickered, and the driver's driving is not hindered.

  In addition, the brake pedal operation, the side brake operation, and the gear position change operation detected by the driving operation detection means for determining the visual recognition request state are all vehicle braking operations by the driver. . That is, based on whether or not the braking operation, which is an essential function of the vehicle, has been performed, it is regarded as a visual recognition request state in which there is a high possibility that the driver intends to visually recognize the display means. For this reason, it is possible to determine the viewing request state with a simple configuration without providing a special means for determining the viewing request state separately.

  The vehicle display device according to the second aspect of the present invention is the vehicle display device according to the first aspect, and further includes a start intention determination unit.

  The start intention determination means is a driving operation detection means that determines whether the driver is in a start transition state where there is a high possibility that the driver intends to start the vehicle or is in a stop continuation state where the possibility that the driver intends to start is low. The determination is made based on the detected driving operation of the driver.

  If the display control means determines that the start intention determination means is in the start transition state in a state in which the predetermined information is displayed on the display means by the detailed display, the visual intent determination means is in the view request state. Even in the situation of determination, when the detailed display is switched to the simple display and it is determined that the start intention determination unit is in the stop continuation state, the visual intention determination unit is determined to be in the visual non-request state. Even then, the detailed display is continued.

  The start intention determining means is in the start transition state when all the driving operations satisfy a predetermined condition among the plurality of driving operations detected by the driving operation detecting means for determining the start transition state. It may be determined that when any one of the driving operations does not satisfy a predetermined condition, it is determined that the vehicle is in the stop continuation state. In this case, for example, when all of the fact that the brake pedal is not operated, the side brake is not operated, and that the gear stage is the traveling stage is detected, it is determined that the vehicle is in the start transition state. When any one of them is not detected, it is determined that the vehicle is in the stop continuation state.

  The visual intent determination means and the start intention determination means may make each determination based on a common driving operation detected by the driving operation detection means, or may make each determination based on different driving operations.

  In the above configuration, when the driver is in a stop continuation state where the possibility that the driver intends to start the vehicle is low, it is determined that the driver is not in a visual recognition non-request state where the driver is not likely to intend to visually check the display means. Even so, priority is given to the stop continuation state, and the detailed display is continuously maintained.

  Here, the necessity of switching from the detailed display to the simple display is not recognized in the stop continuation state in which the parked vehicle has a high possibility of continuing to stop and a low possibility of starting. In addition, when the detailed display is switched to the simple display on condition that the visual non-request state is detected in the stop continuation state, the driver who has no intention to visually recognize the display means tries to visually recognize the display means again. In addition, there is a possibility that a complicated impression is given to the driver without completely switching from the simple display to the detailed display.

  On the other hand, in the above configuration, the detailed display is always continuously maintained in the stop continuation state, so that a complicated impression is not given to the driver.

  Further, in a situation where it is determined that the driver is in a visual recognition request state where there is a high possibility that the driver intends to visually check the display means when the driver is in a start transition state where the possibility that the vehicle is intended to start is high. Even if it exists, priority is given to being in the start transition state, and the detailed display is switched to the simple display. That is, when the vehicle shifts from the stop continuation state in which the detailed display is always maintained to the start transition state, the driver cannot visually recognize the detailed display. For this reason, it is possible to urge the driver who has visually confirmed the detailed display in the stop continuation state to move his / her line of sight away from the display means at the time of starting transition, and display switching that contributes to safe driving can be performed. it can.

  In addition, when the visual intent determination unit and the start intention determination unit make the respective determinations based on the common driving operation detected by the driving operation detection unit, the configuration can be simplified.

  The vehicle display device according to the third aspect of the present invention includes display means, display control means, travel state detection means, line-of-sight direction detection means, visual margin determination means, and visual intent determination means. .

  The display means is disposed in the passenger compartment and is visible to the driver of the vehicle. The display control means switches the predetermined information notified to the driver between the detailed display and the simple display in which the amount of information is more limited than the detailed display, and displays the information on the display means. The traveling state detection means detects the traveling state of the vehicle. The line-of-sight direction detection means detects the line-of-sight direction of the driver. The visibility margin determining means is based on the traveling state of the vehicle detected by the traveling state detecting means to determine whether the driver is in a visually recognizable state with a large margin for visually recognizing the display means or a visually unseen state with a small margin. Judgment. The visual intent determination means determines whether the driver is in a visual recognition required state where the possibility that the driver intends visual recognition of the display means is high, or whether the driver is in a visual recognition non-request state where the possibility of visual recognition is low. The determination is made based on the driver's line-of-sight direction detected by the direction detection means.

  The display control means determines that the visual margin determination means is in a visible state in a state where predetermined information is displayed on the display means by simple display, and determines that the visual intent determination means is in a visual request state. In such a case, the simple display is switched to the detailed display, and the simple display is displayed when it is determined that the visual margin determination means is in a state incapable of visual recognition or when the visual intent determination means is determined to be in a visual non-request state. continue.

  The line-of-sight direction detection means detects the line-of-sight direction of the driver based on, for example, the image of the driver's face or eyeball captured by the camera.

  The visual intent determining means determines, for example, that the state in which the driver's line-of-sight direction is the direction of the display means is a predetermined time or more or a predetermined time ratio or more, and determines that it is a visual recognition request state. When the time ratio is less than the predetermined time ratio, it is determined that the state is not visually required.

  In the above configuration, when the driver is in a visually recognizable state with a lot of room for visually recognizing the display means, and the driver is in a viewing request state where the driver is likely to intend to visually recognize the display means, the simple display is detailed. Switch to display. Therefore, even if the vehicle is traveling, the driver who intends to visually recognize the display means will stop the vehicle if the driver does not lose the safety of driving by viewing the detailed display. Detailed information can be confirmed by the detailed display without being limited to the inside.

  In addition, when the driver is in a state where the driver cannot visually recognize the display means, the simple display with a limited amount of information is continuously maintained. Thereby, since a driver | operator can grasp | ascertain the information displayed on the display means in a short time, a driver | operator's driving | operation is not prevented.

  In addition, when the driver is in a visual non-request state where the driver is not likely to visually recognize the display means, the simple display is continuously maintained regardless of whether the driver has a large or small margin for visually recognizing the display means. The For this reason, when the driver does not need the detailed display, unnecessary switching from the simple display to the detailed display is performed and the driver's view is not flickered, and the driver's driving is not hindered.

  Further, the visual recognition request state is determined based on the driver's line-of-sight direction. For this reason, the simple display can be switched to the detailed display at the direct timing when the driver visually recognizes the display means.

  The vehicle display device according to the fourth aspect of the present invention is the vehicle display device according to the third aspect, further comprising driving operation detection means and start intention determination means.

  The driving operation detection means detects the driving operation of the driver. The start intention determination means is a driving operation detection means that determines whether the driver is in a start transition state where there is a high possibility that the driver intends to start the vehicle or is in a stop continuation state where the possibility that the driver intends to start is low. The determination is made based on the detected driving operation of the driver.

  If the display control means determines that the start intention determination means is in the start transition state in a state in which the predetermined information is displayed on the display means by the detailed display, the visual intent determination means is in the view request state. Even in the situation of determination, when the detailed display is switched to the simple display and it is determined that the start intention determination unit is in the stop continuation state, the visual intention determination unit is determined to be in the visual non-request state. Even then, the detailed display is continued.

  In the above configuration, when the driver is in a stop continuation state where the possibility that the driver intends to start the vehicle is low, it is determined that the driver is not in a visual recognition non-request state where the driver is not likely to intend to visually check the display means. Even so, priority is given to the stop continuation state, and the detailed display is continuously maintained.

  Here, the necessity of switching from the detailed display to the simple display is not recognized in the stop continuation state in which the parked vehicle has a high possibility of continuing to stop and a low possibility of starting. In addition, when the detailed display is switched to the simple display on condition that the visual non-request state is detected in the stop continuation state, the driver who has no intention to visually recognize the display means tries to visually recognize the display means again. In addition, there is a possibility that a complicated impression is given to the driver without completely switching from the simple display to the detailed display.

  On the other hand, in the above configuration, the detailed display is always continuously maintained in the stop continuation state, so that a complicated impression is not given to the driver.

  Further, in a situation where it is determined that the driver is in a visual recognition request state where there is a high possibility that the driver intends to visually check the display means when the driver is in a start transition state where the possibility that the vehicle is intended to start is high. Even if it exists, priority is given to being in the start transition state, and the detailed display is switched to the simple display. That is, when the vehicle shifts from the stop continuation state in which the detailed display is always maintained to the start transition state, the driver cannot visually recognize the detailed display. For this reason, it is possible to urge the driver who has visually confirmed the detailed display in the stop continuation state to move his / her line of sight away from the display means at the time of starting transition, and display switching that contributes to safe driving can be performed. it can.

  According to the present invention, if there is room for visually recognizing the detailed display, the driver can surely visually recognize the detailed display without being limited to when the vehicle is stopped, and the details can be reduced from the simple display. Unnecessary switching to display can be prevented.

Do not remove the sub tank cap at high temperatures as it may cause burns. Please display the specific countermeasures for abnormalities in the vehicle system, including important points for safe handling.

  As shown in FIG. 3 (h), when the notification request determination unit 81 determines that the air pressure in the gear stage switching tank has decreased, the display control unit 85 displays “T / M” in the simple display. "Air pressure drop" is displayed, and "T / M air pressure drop" is displayed on the detailed display, and "Turn on air until this display disappears. If it lights up frequently, please contact the sales company." Display specific countermeasures for system abnormalities.

  Further, as shown in FIG. 3 (i), when the notification request determination unit 81 determines that the clutch pedal has been depressed for a predetermined time or longer after the gears are connected, the display control unit 85 displays “clutch addition” in the simple display. "Caution" is displayed, and "Detailed display" indicates "Clutches are cautioned." And "The clutch may wear out early. Do not put your feet on the clutch pedal while driving." Display advice.

  Next, display control processing executed by the controller 8 of the present embodiment will be described with reference to the flowchart shown in FIG. The controller 8 executes display control processing every predetermined time (for example, every second).

  First, in step S11, it is desirable to notify the driver of information based on the system state of the vehicle 1 detected by the system state sensor 6 and the driving operation of the driver detected by the driving operation sensor 4. The notification request determination unit 81 determines whether or not. If it is determined that the notification request state is not set, this processing is terminated. Moreover, when it determines with it being an alerting | reporting request | requirement state, it transfers to step S12.

  Next, in step S12, based on the vehicle speed of the vehicle 1 detected by the vehicle speed sensor 51, it is determined whether or not the vehicle 1 is stopped (0 km / h). When it is determined that the vehicle 1 is traveling and not stopped, the process proceeds to step S13.

  Next, in step S <b> 13, the visual intent determination unit 82 determines whether or not the brake pedal sensor 41 detects that the brake pedal is operated. When the brake pedal is not operated, the process proceeds to step S14. Next, in step S14, the visual intent determination unit 82 determines whether or not the side brake sensor 42 detects that the side brake is operated. When the side brake is not operated, the process proceeds to step S15. Next, in step S15, the visual intent determination unit 82 determines whether or not the gear position sensor 43 detects that the gear position is neutral. When the brake pedal is not operated (step S13: NO), when the side brake is not operated (step S14: NO), and when the gear stage is other than neutral (step S15: NO) The display control unit 85 corresponds to the notification request state determined by the notification request determination unit 81 because the driver is in a non-viewing request state where the driver is not likely to view the display unit 3 (step S17). A simple display for displaying predetermined information is read from the display information storage unit 7, the read simple display is displayed on the display unit 3 (step S18), and this process is terminated. Further, when the brake pedal is operated (step S13: YES), when the side brake is operated (step S14: YES), and when the gear stage is neutral (step S15: YES), Since the driver is in a viewing request state where the driver is likely to view the display unit 3 (step S16), the process proceeds to step S19 to determine whether the driver is in a visually visible state or in an invisible state. To do.

  Next, in step S19, the visual allowance determining unit 83 determines whether the vehicle speed of the vehicle 1 detected by the vehicle speed sensor 51 is 5 km / h or less. When the vehicle speed exceeds 5 km / h, the driver cannot afford to visually recognize the display unit 3 (step S20), so the display control unit 85 is determined by the notification request determination unit 81. The simple display that displays the predetermined information corresponding to the notification request state is read from the display information storage unit 7, the read simple display is displayed on the display unit 3 (step S18), and the process is terminated. Further, when the vehicle speed is 5 km / h or less, the display control unit 85 is informed by the notification request determining unit 81 because the driver can easily recognize the display unit 3 (step S21). A detailed display for displaying predetermined information corresponding to the requested state is read from the display information storage unit 7, the read detailed display is displayed on the display unit 3 (step S22), and this process is terminated.

  Moreover, when it determines with the vehicle 1 having stopped in step 12, it transfers to step S23. In step S23, the start intention determination unit 84 determines whether or not the brake pedal sensor 41 detects that the brake pedal is operated. When the brake pedal is not operated, the process proceeds to step S24. Next, in step S24, the start intention determination unit 84 determines whether or not the side brake sensor 42 detects that the side brake is operated. When the side brake is not operated, the process proceeds to step S25. Next, in step S25, the start intention determination unit 84 determines whether or not the gear position sensor 43 has detected that the gear position is the traveling position. When the brake pedal is not operated (step S23: NO), when the side brake is not operated (step S24: NO), and when the gear stage is the traveling stage (step S25: YES) Since it is a start transition state in which the driver is likely to start the vehicle 1 (step S26), the display control unit 85 has a predetermined response corresponding to the notification request state determined by the notification request determination unit 81. A simple display for displaying information is read from the display information storage unit 7, the read simple display is displayed on the display unit 3 (step S18), and this process is terminated. Further, when the brake pedal is operated (step S23: YES), when the side brake is operated (step S24: YES), and when the gear stage is other than the traveling stage (step S25: NO). Is a stop continuation state in which it is unlikely that the driver intends to start the vehicle 1 (step S27). Therefore, the display control unit 85 corresponds to the notification request state determined by the notification request determination unit 81. The detailed display for displaying the information is read from the display information storage unit 7, the read detailed display is displayed on the display unit 3 (step S22), and the process is terminated.

  In the display control process, when the notification request determination unit 81 determines that the notification request state is established, the predetermined information corresponding to the notification request state determined by the notification request determination unit 81 is displayed in detail display or simple display. The When the notification request determination unit 81 determines that the notification request state is not set, the display unit 3 is in a non-display state.

  When the driver is operating the brake pedal, operating the side brake, or changing the gear stage to neutral while the vehicle 1 is traveling, it is determined that the viewing request state is established. Further, when the vehicle 1 is traveling and is in a view request state, if the vehicle speed of the vehicle 1 is 5 km / h or less, it is determined that the vehicle 1 is in a viewable state and is displayed by a detailed display. Further, when the vehicle 1 is running, if the driver does not operate the brake pedal or the side brake and operates the gear stage to a position other than neutral, it is determined that the visual recognition is not requested, and simple display is performed. Is displayed. Further, when the vehicle 1 is traveling and in the visual recognition request state, if the vehicle speed of the vehicle 1 exceeds 5 km / h, it is determined that the vehicle 1 is in an invisible state and is displayed by simple display. For this reason, in the state displayed on the display unit 3 by the simple display, when it is determined that the visual recognition is possible and the visual recognition is requested, the simple display is switched to the detailed display and the visual recognition is not performed. When it is determined that it is in a possible state, or when it is determined that it is in a visual non-request state, the simple display is continuously maintained.

  Further, when the vehicle 1 is stopped, if the driver operates the brake pedal, operates the side brake, or operates the gear stage other than the traveling stage, it is determined that the vehicle is in the stop continuation state. , Displayed by detail display. When the vehicle 1 is stopped, if the driver does not operate the brake pedal, does not operate the side brake, and changes the gear stage to the traveling stage, it is determined that the vehicle is in the start transition state, and the simple display Is displayed. For this reason, in the state displayed on the display unit 3 by the detailed display, when it is determined that the vehicle is in the start transition state, it is determined whether or not the visual intention determination unit 82 determines that the visual request state is present. Regardless of whether or not the state is determined to be the request state, the detailed display is switched to the simple display, and when it is determined that the stop continuation state is present, the visual intent determination unit 82 determines that the visual request state is present. Regardless of whether it is a situation or a situation where it is determined that it is in a visual non-request state, the detailed display is continuously maintained.

  Next, a second embodiment of the present invention will be described with reference to FIGS.

  FIG. 5 is a block configuration diagram of a vehicle including the vehicle display device according to the second embodiment, and FIG. 6 is a flowchart showing display control processing according to the second embodiment. As shown in FIG. 5, the vehicle display device 21 provided in the vehicle 11 according to the present embodiment includes a display unit (display unit) 3, a driving operation sensor (driving operation detection unit) 4, and a camera (line-of-sight direction). Detection means) 22, a running state sensor (running state detection means) 5, a system state sensor 6, a display information storage unit 7, and a controller 80. The controller 80 includes a notification request determination unit 81, a gaze direction determination unit (gaze direction detection unit) 23, a visual intent determination unit (visual intent determination unit) 86, a visual margin determination unit (visual margin determination unit) 83, The vehicle has a start intention determination unit (start intention determination unit) 84 and a display control unit (display control unit) 85. The controller 80 receives signals output from the camera 22, the running state sensor 5, and the system state sensor 6. The components common to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The camera 22 and the line-of-sight direction determination unit 23 constitute a line-of-sight direction detection unit of the present invention and detect the driver's line-of-sight direction. The camera 22 captures the driver's eyeball or face and outputs video data including imaging information to the controller 80. The line-of-sight direction determination unit 23 determines the line-of-sight direction of the driver based on video data input from the camera 22.

  Based on the driver's line-of-sight direction determined by the line-of-sight direction determination unit 23, the visual intent determination unit 86 is in a visual request state where the driver is likely to intend to view the display unit 3, or is visually It is determined whether or not it is a visual non-request state that is unlikely to be intended. In the present embodiment, it is determined whether or not the ratio of the time during which the driver's line of sight is facing the display unit 3 in a predetermined time (2 seconds) exceeds a reference value (for example, 50%). When the time ratio in which the line of sight faces the display unit 3 exceeds the reference value, it is determined that it is in the visual recognition request state, and the time ratio in which the driver's line of sight faces the display unit 3 in a predetermined time is equal to or less than the reference value. When it is, it determines with it being a visual recognition non-request state.

  Note that the visual intent determination unit 86 is in a visual recognition request state or in a visual non-request state depending on whether or not the ratio of the time during which the driver's line of sight faces the display unit 3 in a predetermined time exceeds a reference value. However, other determination criteria may be provided as criteria for determining whether the state is a visual recognition request state or a visual non-request state. For example, it is determined whether or not the time when the driver's line of sight faces the display unit 3 exceeds a predetermined time (for example, 2 seconds), and the time when the driver's line of sight faces the display unit 3 is set to the predetermined time. When it exceeds, it may be determined that the state is in a visual recognition required state, and may be determined as being in a visual non-request state when the time during which the driver's line of sight faces the display unit 3 is a predetermined time or less. In addition, the visual intent determination unit 86 determines whether or not the number of times the driver's line of sight faces the display unit 3 in a predetermined time exceeds the reference number, and the driver's line of sight faces the display unit 3 in the predetermined time. When the number of times of the vehicle exceeds the reference number of times, it is determined that the state is a visual recognition required state. May be determined. Further, the visual intent determination unit 86 may provide a plurality of determination criteria as to whether the visual inspecting state is in the visual requesting state or in the visual non-requesting state. In addition, the visual intent determination unit 86 determines that the driver is not in the visual non-request state when the driver's line of sight is off the display unit 3 in the state in which the visual recognition request state is determined. If the driver's line of sight deviates from the display unit 3 for a long time that it can be determined that there is no intention of visually recognizing the unit 3, it may be determined that the state is not required to be viewed. As a result, the detailed display and the simple display are not frequently switched, so that the driver does not have a complicated impression.

  Next, display control processing executed by the controller 80 of the present embodiment will be described with reference to the flowchart shown in FIG. The controller 80 executes display control processing every predetermined time (for example, every second).

  First, in step S31, it is desirable to notify the driver of information based on the system state of the vehicle 11 detected by the system state sensor 6 and the driving operation of the driver detected by the driving operation sensor 4. The notification request determination unit 81 determines whether or not. If it is determined that the notification request state is not set, this processing is terminated. Moreover, when it determines with it being a notification request | requirement state, it transfers to step S32.

  Next, in step S32, based on the vehicle speed of the vehicle 11 detected by the vehicle speed sensor 51, it is determined whether or not the vehicle 11 is stopped (0 km / h). When it is determined that the vehicle 11 is traveling and not stopped, the process proceeds to step S33.

  Next, in step S33, the visual intent determination unit 86 determines whether or not the time ratio during which the driver's line of sight faces the display unit 3 in 2 seconds exceeds 50%. When the time ratio in which the driver's line of sight is facing the display unit 3 in 2 seconds is 50% or less, the driver is in a non-viewing-required state with a low possibility that the driver intends to view the display unit 3 ( In step S34), the display control unit 85 reads a simple display that displays predetermined information corresponding to the notification request state determined by the notification request determination unit 81 from the display information storage unit 7, and displays the read simple display on the display unit 3. (Step S35), and the process is terminated. In addition, when the time ratio in which the driver's line of sight is facing the display unit 3 in 2 seconds exceeds 50%, the driver is likely to intend to view the display unit 3 and is in a viewing request state. Therefore (step S36), the process proceeds to step S37 in order to determine whether it is a visually recognizable state or an invisible state.

  Next, in step S <b> 37, the visual allowance determining unit 83 determines whether or not the vehicle speed of the vehicle 11 detected by the vehicle speed sensor 51 is 5 km / h or less. When the vehicle speed exceeds 5 km / h, the driver cannot afford to visually recognize the display unit 3 (step S38), and the display control unit 85 determines the notification request determination unit 81. A simple display that displays predetermined information corresponding to the notification request state is read from the display information storage unit 7, the read simple display is displayed on the display unit 3 (step S35), and the process is terminated. Further, when the vehicle speed is 5 km / h or less, the display control unit 85 is informed by the notification request determining unit 81 because the driver can afford to visually recognize the display unit 3 (step S39). A detailed display for displaying predetermined information corresponding to the requested state is read from the display information storage unit 7, the read detailed display is displayed on the display unit 3 (step S40), and the process is terminated.

  Moreover, when it determines with the vehicle 11 being stopped in step 32, it transfers to step S41. In step S41, the start intention determination unit 84 determines whether or not the brake pedal sensor 41 detects that the brake pedal is operated. When the brake pedal is not operated, the process proceeds to step S42. Next, in step S42, the start intention determination unit 84 determines whether or not the side brake sensor 42 detects that the side brake is operated. When the side brake is not operated, the process proceeds to step S43. Next, in step S43, the start intention determination unit 84 determines whether or not the gear position sensor 43 has detected that the gear position is the traveling position. When the brake pedal is not operated (step S41: NO), when the side brake is not operated (step S42: NO), and when the gear stage is the traveling stage (step S43: YES) Since it is a start transition state in which the driver is likely to start the vehicle 11 (step S44), the display control unit 85 has a predetermined response corresponding to the notification request state determined by the notification request determination unit 81. A simple display for displaying information is read from the display information storage unit 7, the read simple display is displayed on the display unit 3 (step S35), and the process is terminated. Further, when the brake pedal is operated (step S41: YES), when the side brake is operated (step S42: YES), and when the gear stage is other than the traveling stage (step S43: NO). Is a stop continuation state in which it is unlikely that the driver intends to start the vehicle 11 (step S45). Therefore, the display control unit 85 corresponds to the notification request state determined by the notification request determination unit 81. The detailed display for displaying the information is read from the display information storage unit 7, the read detailed display is displayed on the display unit 3 (step S40), and the process is terminated.

  In the display control process, when the notification request determination unit 81 determines that the notification request state is established, the predetermined information corresponding to the notification request state determined by the notification request determination unit 81 is displayed in detail display or simple display. The When the notification request determination unit 81 determines that the notification request state is not set, the display unit 3 is in a non-display state.

  Further, in a state where the vehicle 11 is traveling, when the driver turns his / her line of sight toward the display unit 3 at a time ratio exceeding 50% in 2 seconds, it is determined that the state is a visual recognition request state. Further, when the vehicle 11 is traveling and is in a view request state, if the vehicle speed of the vehicle 11 is 5 km / h or less, the vehicle 11 is determined to be in a viewable state and is displayed by a detailed display. In addition, when the vehicle 11 is traveling, if the driver only turns his / her line of sight to the display unit 3 for 2 seconds, it is determined that the user is not required to view and is displayed by simple display. Is done. Further, when the vehicle 11 is traveling and is in a visual recognition request state, if the vehicle speed of the vehicle 11 exceeds 5 km / h, it is determined that the vehicle 11 is in an invisible state and is displayed by simple display. For this reason, in the state displayed on the display unit 3 by the simple display, when it is determined that the visual recognition is possible and the visual recognition is requested, the simple display is switched to the detailed display and the visual recognition is not performed. When it is determined that it is in a possible state, or when it is determined that it is in a visual non-request state, the simple display is continuously maintained.

  Further, when the vehicle 11 is stopped, if the driver operates the brake pedal, operates the side brake, or operates the gear stage other than the traveling stage, it is determined that the vehicle is in the stop continuation state. , Displayed by detail display. Further, when the vehicle 11 is stopped, if the driver does not operate the brake pedal, does not operate the side brake, and changes the gear stage to the traveling stage, it is determined that the vehicle is in the start transition state, and the simple display is performed. Is displayed. For this reason, in the state displayed on the display unit 3 by the detailed display, if it is determined that the vehicle is in the start transition state, it is determined whether or not the visual intention determination unit 86 determines that it is in the visual request state. Regardless of whether or not the state is determined to be the request state, the detailed display is switched to the simple display, and when it is determined that the state is the stop continuation state, the visual intent determination unit 86 determines that the state is the visual request state. Regardless of whether it is a situation or a situation where it is determined that it is in a visual non-request state, the detailed display is continuously maintained.

  In this embodiment, since the visual recognition request state and the visual non-request state are determined based on the driver's line-of-sight direction, the simple display can be switched to the detailed display at a direct timing when the driver visually recognizes the display unit 3. it can.

  Next, a third embodiment of the present invention will be described with reference to FIGS.

  FIG. 7 is a block diagram of a vehicle provided with the vehicle display device according to the third embodiment, and FIG. 8 is a flowchart showing display control processing according to the third embodiment.

  As shown in FIG. 7, the vehicle display device 20 provided in the vehicle 10 according to this embodiment includes a display unit (display unit) 3, a driving operation sensor (driving operation detection unit) 40, and a traveling state sensor ( Travel state detection means) 50, system state sensor 6, display information storage unit 7, and controller 9. The components common to the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The driving operation sensor 40 includes a vehicle speed sensor 45 and an accelerator pedal sensor 46. The vehicle speed sensor 45 is provided for the driver to detect a driving operation for braking the vehicle 10, detects the vehicle speed of the vehicle 10, and outputs a signal including information on the detected vehicle speed to the controller 9. The accelerator pedal sensor 46 detects whether or not the accelerator pedal is operated, and outputs a signal including information on the detected state of the accelerator pedal to the controller 9.

  The traveling state sensor 50 detects the traveling state of the vehicle 10. The traveling state sensor 50 includes a steering angle sensor 52. The steering angle sensor 52 detects the steering angle input to the steering, and outputs a signal including the detected steering angle to the controller 9.

  The controller 9 includes a notification request determination unit 81, a driving operation determination unit 91, a visual intent determination unit (visual intent determination unit) 92, a travel state determination unit 93, and a visual margin determination unit (visual margin determination unit) 94. The vehicle has a start intention determination unit (start intention determination unit) 95 and a display control unit (display control unit) 85.

  Based on the vehicle speed detected by the vehicle speed sensor 45, the driving operation determination unit 91 determines whether or not the vehicle speed of the vehicle 10 is equal to or lower than a predetermined speed, and determines whether or not the deceleration occurs within a predetermined range. . The driving operation determination unit 91 determines whether or not the predetermined speed is 20 km / h or less. The predetermined speed is not limited to 20 km / h, but is preferably about 15 km / h to 25 km / h. The deceleration within the predetermined range is a deceleration that can be determined as a stop brake, and the deceleration that can be determined as a sudden brake is excluded.

  When the driving operation determination unit 91 determines that the vehicle speed of the vehicle 10 is 20 km / h or less and the driving operation determination unit 91 determines that the deceleration of the vehicle 10 is within a predetermined range. When the driving operation determination unit 91 determines that the driver is in a viewing request state where the driver is likely to view the display unit 3 and the vehicle speed of the vehicle 10 exceeds 20 km / h. Alternatively, when the driving operation determination unit 91 determines that the deceleration of the vehicle 10 is not within the predetermined range, it is determined that the driver is in a non-viewing request state where it is unlikely that the driver intends to view the display unit 3. .

  The driving operation sensor 40 may further include a brake pedal sensor 41 and a gear position sensor 43. In this case, the visual intent determining unit 92 determines that the visual intent request state is detected when the brake pedal sensor 41 detects that the brake pedal is operated or when the gear position sensor 43 detects that the gear is neutral. However, when the brake pedal sensor 41 detects that the brake pedal is not operated, and the gear position sensor 43 detects that the gear position is other than neutral, it may be determined that the visual recognition non-request state is present. . This makes it possible to eliminate deceleration states where it is difficult to recognize the visual intent, such as when the vehicle is on a steep uphill slope or when the side brake is operated at medium speed. It is possible to determine the visual recognition requested state and the visual non-requested state based on the deceleration state caused by the braking operation that has been changed.

  The traveling state determination unit 93 determines whether or not the vehicle 10 is in a straight traveling state based on the steering angle of the steering detected by the steering angle sensor 52. In the present embodiment, the traveling state determination unit 93 determines that the vehicle 10 is traveling straight when the steering angle detected by the steering angle sensor 52 is less than a predetermined angle, and the steering angle detected by the steering angle sensor 52. When the vehicle is equal to or greater than a predetermined angle, it is determined that the vehicle 10 is not in a straight traveling state. The traveling state determination unit 93 is not limited to determining whether or not the steering angle sensor 52 is greater than or equal to a predetermined angle based on the steering angle of the steering detected by the steering angle sensor 52. It is determined whether or not the input is detected a predetermined number of times or more within a predetermined time. When the input to the steering is detected a predetermined number of times or more within the predetermined time, it is determined that the vehicle 10 is not in a straight traveling state, and the steering is performed. May be determined that the vehicle 10 is in a straight traveling state when less than a predetermined number of times is detected within a predetermined time.

  When the traveling state determination unit 93 determines that the vehicle 10 is in a straight traveling state, the visual recognition margin determination unit 94 determines that the vehicle 10 is in a visually recognizable state with a large margin for visually recognizing the display unit 3. When the traveling state determination unit 93 determines that the vehicle is not in the straight traveling state, it is determined that the driver is in an invisible state with little margin for visually recognizing the display unit 3.

  When the accelerator pedal sensor 46 detects that the accelerator pedal is not operated, the start intention determination unit 95 determines that the vehicle is in a stop-continuation state, and when the accelerator pedal sensor 46 detects that the accelerator pedal is operated. It is determined that the vehicle is in a start transition state.

  Next, display control processing executed by the controller 9 of this embodiment will be described with reference to the flowchart shown in FIG. The controller 9 executes display control processing every predetermined time (for example, every second).

  First, in step S51, it is desirable to notify the driver of information based on the system state of the vehicle 10 detected by the system state sensor 6 and the driving operation of the driver detected by the driving operation sensor 40. The notification request determination unit 81 determines whether or not. If it is determined that the notification request state is not set, this processing is terminated. Moreover, when it determines with it being a notification request | requirement state, it transfers to step S52.

  Next, in step S52, based on the vehicle speed of the vehicle 10 detected by the vehicle speed sensor 45, it is determined whether or not the vehicle 10 is stopped (0 km / h). When it is determined that the vehicle 10 is traveling and not stopped, the process proceeds to step S53.

  Next, in step S53, the driving operation determination unit 91 determines whether the vehicle speed of the vehicle 10 detected by the vehicle speed sensor 45 is 20 km / h or less. When the vehicle speed is 20 km / h or less, the process proceeds to step S54. Next, in step S54, based on the vehicle speed of the vehicle 10 detected by the vehicle speed sensor 45, the driving operation determination unit 91 determines whether the deceleration is within a predetermined range. When the vehicle speed exceeds 20 km / h (step S53: NO) and when the vehicle speed is not within a predetermined range (step S54: NO), the driver may intend to view the display unit 3. Since the display non-request state is low (step S55), the display control unit 85 reads from the display information storage unit 7 a simple display that displays predetermined information corresponding to the notification request state determined by the notification request determination unit 81. Then, the read simple display is displayed on the display unit 3 (step S56), and this process is terminated. When the vehicle speed is 20 km / h or less (step S53: YES), and when the vehicle speed is within a predetermined range (step S54: YES), the driver intends to visually recognize the display unit 3. Since the viewing request state is highly likely (step S57), the process proceeds to step S58 in order to determine whether the viewing is possible or not.

  Next, in step S58, the traveling state determination unit 93 determines whether or not the steering angle detected by the steering angle sensor 52 is greater than or equal to a predetermined angle. If the steering angle is equal to or greater than the predetermined angle, the vehicle 10 is not in a straight traveling state, and is in a state where the driver cannot easily see the display unit 3 (step S59). A simple display that displays predetermined information corresponding to the notification request state determined by the request determination unit 81 is read from the display information storage unit 7, and the read simple display is displayed on the display unit 3 (step S56). Exit. Further, when the steering angle is less than the predetermined angle, the vehicle 10 is in a straight traveling state and is in a visually recognizable state with a lot of room for the driver to visually recognize the display unit 3 (step S60). A detailed display that displays predetermined information corresponding to the notification request state determined by the notification request determination unit 81 is read from the display information storage unit 7, and the read detailed display is displayed on the display unit 3 (step S61). The process ends.

  If it is determined in step 52 that the vehicle 10 is stopped, the process proceeds to step S62. In step S62, the start intention determination unit 95 determines whether or not the accelerator pedal sensor 46 detects that the accelerator pedal is operated. When the accelerator pedal is operated, the display control unit 85 determines that the notification request determination unit 81 determines that the driver is likely to start the vehicle 10 (step S63). A simple display that displays predetermined information corresponding to the notification request state is read from the display information storage unit 7, the read simple display is displayed on the display unit 3 (step S56), and this process is terminated. Further, when the accelerator pedal is not operated, it is in a stop continuation state where it is unlikely that the driver intends to start the vehicle 10 (step S64). Therefore, the display control unit 85 includes the notification request determination unit 81. A detailed display for displaying predetermined information corresponding to the determined notification request state is read from the display information storage unit 7, the read detailed display is displayed on the display unit 3 (step S61), and the process is terminated.

  In the display control process, when the notification request determination unit 81 determines that the notification request state is established, the predetermined information corresponding to the notification request state determined by the notification request determination unit 81 is displayed in detail display or simple display. The When the notification request determination unit 81 determines that the notification request state is not set, the display unit 3 is in a non-display state.

  Further, when the vehicle 10 is traveling, when the driver brakes the vehicle 10 and the vehicle speed is 20 km / h or less and the deceleration is within a predetermined range, it is determined that the state is in the visual recognition required state. . Further, when the vehicle 10 is traveling and is in a visual recognition request state, if the driver is steering the steering by less than a predetermined angle, it is determined that the vehicle is in a visual recognition state and is displayed by a detailed display. In addition, when the vehicle 10 is traveling, if the vehicle speed exceeds 20 km / h or if the vehicle 10 is not decelerated within a predetermined range (including acceleration), it is determined that the state is not required for visual recognition. Displayed by display. In addition, when the vehicle 10 is running and the driver is in a visual recognition request state, if the driver is steering the steering by a predetermined angle or more, it is determined that the vehicle is not visually recognized and is displayed by a simple display. For this reason, in the state displayed on the display unit 3 by the simple display, when it is determined that the visual recognition is possible and the visual recognition is requested, the simple display is switched to the detailed display and the visual recognition is not performed. When it is determined that it is in a possible state, or when it is determined that it is in a visual non-request state, the simple display is continuously maintained.

  Further, when the vehicle 10 is stopped, when the driver does not operate the accelerator pedal, it is determined that the vehicle is in the stop continuation state and is displayed by a detailed display. Further, when the vehicle 10 is stopped, when the driver starts operating the accelerator pedal, it is determined that the vehicle is in a start transition state, and is displayed by simple display. For this reason, in the state displayed on the display unit 3 by the detailed display, if it is determined that the vehicle is in the start transition state, it is determined whether or not the visual intention determination unit 92 determines that it is in the visual request state. Regardless of whether or not the state is determined to be in the requested state, when the detailed display is switched to the simple display and it is determined that the state is the stop continuation state, the visual intent determination unit 92 determines that the visual request state is present. Regardless of whether it is a situation or a situation where it is determined that it is in a visual non-request state, the detailed display is continuously maintained.

It is determined whether it has become brighter than a predetermined brightness from a state below that brightness.

  The visual recognition margin determination unit is based on the traveling state of the vehicle detected by the traveling state sensor to determine whether the driver is in a visually recognizable state with a large margin for visually recognizing the display unit 3 or a small incapable visual recognition state. Judgment. The visual recognition margin determination unit determines that the vehicle speed detected by the vehicle speed sensor 51 is 5 km / h or less, and that the vehicle is in a straight traveling state based on the steering angle of the steering detected by the steering angle sensor 52. The vehicle state based on the image of the surroundings of the vehicle imaged by the camera outside the vehicle, the vehicle state being determined that the road surface is in a maintenance state based on the vertical acceleration of the vehicle body detected by the acceleration sensor However, the driving state determination unit has determined that the course has not changed, and the driving state determination unit has determined that the brightness outside the vehicle detected by the autolight sensor does not change above and below the predetermined brightness. It is determined that the vehicle is in a visible state when the condition is satisfied, and the traveling state determination unit determines that the vehicle is not in the straight traveling state based on the steering angle of the steering detected by the steering angle sensor 52. Based on the acceleration in the vertical direction of the vehicle body detected by the acceleration sensor, the traveling state determination unit determines that the road surface is in an unprepared state, and based on the surrounding image captured by the outside camera, the vehicle At least one of the conditions that the traveling state determination unit determines that a change has been made, and that the traveling state determination unit has determined that the brightness outside the vehicle detected by the autolight sensor has changed above and below a predetermined brightness. When satisfy | filling, it determines with it being a visually invisible state. In addition, when the driving condition determination unit determines that the brightness outside the vehicle detected by the autolight sensor has changed above and below the specified brightness, the brightness outside the vehicle changes greatly in a short time, such as entering and exiting a tunnel. Since there is a possibility that a state where there is little room for visually recognizing the display unit 3 for the person, the viewing margin determination unit determines that the brightness outside the vehicle has changed above and below the predetermined brightness, The driver may determine that the driver is in an invisible state for a predetermined time (for example, 3 seconds) necessary for eyeball adaptation.

  The start intention determination unit determines whether the driver is in a start transition state where there is a high possibility that the driver intends to start the vehicle or in a stop continuation state where the possibility that the driver intends to start is low. The determination is made based on information inputted from the brake sensor 41, the side brake sensor 42, the gear position sensor 43, the accelerator pedal sensor 46, and the vehicle state sensor. The start intention determination unit detects that the brake pedal sensor 41 detects that the brake pedal is not operated, detects that the side brake sensor 42 detects that the side brake is not operated, and determines that the gear stage is the traveling stage.

Continuously stop when at least one of the conditions that the interior light is detected by the interior light sensor and that the seatbelt sensor detects that the driver's seat belt is fastened It is determined that it is in a state.

  The display control unit 85 performs the same processing as in the first embodiment. In addition, the display control unit 85 switches the simple display to the detailed display when the detailed display request switch is on in a state where the display is displayed on the display unit 3 by the simple display. As a result, the driver can confirm the detailed display at a desired timing. In addition, the driver can check the correspondence between the simple display and the detailed display. In addition, the display control unit 85 switches the detailed display to the simple display when the simple display request switch is turned on in the state of being displayed on the display unit 3 by the detailed display. As a result, the driver can confirm the simple display at a desired timing. In addition, the driver can check the correspondence between the simple display and the detailed display.

  The vehicle display device may be provided with a slope start assist device as a driving operation sensor and a traveling state sensor. The slope start assist device is turned on when the brake pedal is depressed for 2 seconds or more with the side brake released, the gear is not neutral, the vehicle speed is 5 km / h or more, the side brake is When the switch to be pulled or released is operated, it is set to off. When the slope start assist device is set to ON, the brake pedal and the side brake are not operated, but the state where the brake pedal is operated is maintained. The visual intent determination unit determines that the visual recognition request state is satisfied when the slope start assisting device is set to ON, and is a time when all of the above conditions for determining the visual non-request state are satisfied. When the auxiliary device is set to OFF, it is determined that it is in a visually unrequired state. Even if the above-mentioned condition for determining the visibility state is not satisfied, the visual recognition margin determination unit determines that the visual start state is on when the slope start assist device is set to ON, and assists in starting the slope. When the device is set to off, it is determined that the device is in an invisible state. The start intention determination unit determines that the vehicle is in a stop continuation state when the hill start assist device is set to OFF, and satisfies all of the above-described conditions for determining the start transition state. When the device is set to OFF, it is determined that the vehicle is in a start transition state. Further, the slope start assist device may be configured to be turned on when the vehicle speed is 0 km / h, and to be turned off when the vehicle speed is not 0 km / h. In such a configuration, the visual recognition margin determination unit may not perform determination based on the state detected by the steering angle sensor 52, the acceleration sensor, the outside camera, or the auto light sensor.

  In addition, the various sensors used for the determination of the visual recognition request state and the visual non-request state in the fourth embodiment, the various sensors used for the visual recognition state and the visual inability state, the start transition state, and the stop continuation state are determined. Only a part of the various sensors may be provided, and the above determination may be performed based on the provided sensors.

  As described above, in the first to fourth embodiments of the present invention, in a state in which predetermined information is displayed on the display unit 3 by simple display, the driver has a lot of room for viewing the display unit 3. The simple display is switched to the detailed display when the state is a visual recognition request state in which it is possible and the driver is likely to intend to visually recognize the display unit 3. For this reason, even if the vehicle is traveling, the driver who intends to visually recognize the display unit 3 is not allowed to lose the safety of driving by visually confirming the detailed display. Detailed information by detailed display can be confirmed without being limited to when the vehicle is stopped.

  In addition, in a state where predetermined information is displayed on the display unit 3 by simple display, when the driver is in an invisible state where there is little room for viewing the display unit 3, the simple display with a limited amount of information continues. Maintained. Thereby, since a driver | operator can grasp | ascertain the information displayed on the display part 3 in a short time, a driver | operator's driving | operation is not prevented.

  Further, in a state in which predetermined information is displayed on the display unit 3 by simple display, the display unit 3 is visually recognized when the driver is in a non-viewing request state where it is unlikely that the driver intends to view the display unit 3. Regardless of whether the driver has more or less margin, the simple display is continuously maintained. For this reason, when the driver does not need the detailed display, unnecessary switching from the simple display to the detailed display is performed and the driver's view is not flickered, and the driver's driving is not hindered.

  Further, in a state where predetermined information is displayed on the display unit 3 by the detailed display, when the driver is in the stop continuation state where the possibility that the driver intends to start the vehicle is low, the driver visually recognizes the display unit 3. Even in a situation in which it is determined that the intention non-viewing state is unlikely to be intended, priority is given to the stop continuation state, and the detailed display is continuously maintained.

  Here, in a state where the predetermined information is displayed on the display unit 3 by the detailed display, in the stop continuation state where the possibility that the stopped vehicle is likely to continue the stop is low and the possibility of starting is low, the detailed display is simplified to the simple display. There is no need to switch to. In addition, when the detailed display is switched to the simple display under the condition that the visual recognition non-request state is detected in the stop continuation state, the driver who has no intention to visually recognize the display unit 3 tries to visually recognize the display unit 3 again. In such a case, there is a possibility that a complicated impression is given to the driver without completely switching from the simple display to the detailed display.

  On the other hand, in the above-described embodiment of the present invention, in the state where the predetermined information is displayed on the display unit 3 by the detailed display, the detailed display is always maintained if it is the stop continuation state. It does not give a complicated impression to the person.

  Further, in a state where predetermined information is displayed on the display unit 3 by the detailed display, when the driver is in a start transition state where there is a high possibility that the driver intends to start the vehicle, the driver views the display unit 3 visually. Even in a situation where it is determined that the viewing request state is likely to be intended, the start display state is prioritized and the detailed display is switched to the simple display. That is, when the vehicle shifts from the stop continuation state in which the detailed display is always maintained to the start transition state, the driver cannot visually recognize the detailed display. For this reason, it is possible to urge the driver who has visually confirmed the detailed display in the stop continuation state to move his / her line of sight away from the display means at the time of starting transition, and display switching that contributes to safe driving can be performed. it can.

  As mentioned above, although the embodiment to which the invention made by the present inventor is applied has been described, the present invention is not limited by the discussion and the drawings that form part of the disclosure of the present invention according to this embodiment. That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.

  For example, in the configuration of the above embodiment, when the display control unit 85 determines that the start intention determination unit is in the start transition state in a state where the predetermined information is displayed on the display unit 3 by the detailed display, the display control unit 85 immediately displays the detailed display. Switching to simple display is not limited to this. For example, the display control unit 85 switches the detailed display to the simple display when the start intention determination unit continuously determines that it is in the start transition state after a predetermined time (for example, 5 seconds), and the start intention determination unit The detailed display may be continued when it is not determined continuously after a predetermined time that the vehicle is in the start transition state. Further, when the start intention determination unit continuously determines that the start transition state is in the start transition state for a predetermined time (for example, 5 seconds), the detailed display is switched to the simple display, and when the start intention determination unit is in the start transition state, If the determination is not made continuously, the detailed display may be continued. Thereby, the display of the detailed display can be continuously maintained without needlessly switching to the simple display.
